The amount of space set aside on a server for a Web site. Most ISPs allocate free Web space for their users. The minimum amount offered is usually 10 to 12 megabytes, which is ample space for most people's needs. Check with your ISP: some ISPs offer unlimited Web space; some specify that you can't use the space for commercial purposes; some aren't set up to allow for certain kinds of programs (such as e-commerce applications); and some do not allow content that is copyrighted by a third-party or could be considered offensive.
